The serious errors of workers when painting markings on road surfaces are enough to make you do a double-take - but hopefully behind the wheel or they could end up causing more than a titter.

Of course everyone makes mistakes - and we at Cornwalll Live are certainly not above the occasional errant typo.

But most people probably get away with their errors at work going unnoticed, or possibly catching the eye of a colleague or two - and, with any luck, not their boss.

However those working to repair and maintain Cornwall's roads are never likely to be so fortunate.

And after a section of double yellow and single white lines attracted attention of the wrong kind at Hayle, we looked back at the most recent mistakes to appear on our streets.

Here are the most notable examples:

Last year, pointless double yellow lines painted across the middle of a road at Threemilestone Industrial Estate were removed after Cornwall Council accepted it was "highly unlikely" anyone would try to park there.

Business owners at the estate on the outskirts of Truro were left baffled after the lines were painted on the road last year.

Among them was Mark Mitchell, from the interior design business Stylehom, who branded the lines "obviously unsuitable" and said it was "beyond belief" they had put down in the first place.

Cornwall Council said although the lines were "technically correct" it accepted that it was "highly unlikely" anyone would try to park there.

In a statement, the local authority said the road used had been extended but the traffic order for the area had not been updated.

It read: "The developer was not required to amend the traffic order to extend the waiting restrictions along the new road, so legally, the current order still only runs to the former turning head.

"The yellow lines across the road, whilst appearing to be an unfortunate error, are in fact technically correct.

"However, we recognise that it is highly unlikely that anyone would park a vehicle across the highway at this point, and we will therefore remove the offending section and apply transverse markings to denote the end of the restriction adjacent to the kerb."

Within the same month an embarrassing spelling mistake made by a contractor outside one of Cornwall's best performing schools was put down to "human error".

Western Power Distribution (WPD) confirmed the misspelling of 'school' on safety markings outside Truro High School was a genuine mistake and not a prank.

This contractor might need to go back to shchool, or rather school

A member of staff from Kier Group, which had been contracted by WPD, made the error after works were carried out at the site.

In a bitter irony, all students who took A-level English at the school achieved A* or A grades this year. Unfortunately, they weren't around to assist the worker who added an extra 'h' in 'school' while painting on a section of the road that had been resurfaced.

A statement released by WPD said: "Western Power Distribution would like to apologise for the mistake made to the wording outside of the school, which we can only assume was human error.

"Our contractors, the Kier Group completed the reinstatement works which involved the laying of new tarmac as well as replacing missing letters on the road surface.

"We have taken this up with Kier who will rectify this mistake as a matter of urgency."

Getting in on the joke, the headmaster of Truro High School, Glenn Moodie, said he was relieved to see the mistake had been corrected and offered help to road repair teams.

He added: "Our A Level students have just achieved a fantastic set of results with 100 per cent of those taking English getting grade A.

"If the road repair team need any advice on spellings in the future, we would be more than happy to help."

The mistake was corrected within days

And this week we had the curious case of possibly the shortest section of lines ever.

A new bit of tarmac was laid after work was carried out on a gas main. But the workers responsible for finishing off the surface only painted the lines on the new bit - leaving a curious eye-popping section on Guildford Road in Hayle.

It would appear that old lines on the tarmac either side have faded so much over the years that some have forgotten they were there in the first place. Some members of the Facebook community group, Anything Hayle, even pondered whether second-hand asphalt was being used.

Cornwall Council pointed the finger at Wales and West Utilities, which clarified that it replaced the lines when it replaced the patch of asphalt, in line with its legal agreement with the council.

But Hayle is not alone in that respect, although those behind this instance can only be assumed to be the same parties.
